Adani Enterprises Ltd. hired seven banks including Citigroup Inc. and Bank of America Corp. to help it raise as much as $600 million selling shares to institutional investors, said two people with knowledge of the matter.

Adani Enterprises Ltd. , India’s biggest coal importer, may sell shares in a unit that holds mining rights in the Asia-Pacific region to international investors and use the proceeds to add energy assets.

Adani Enterprises Ltd. is in talks with Hancock Coal about sharing a rail line in Queensland state to transport the fuel used in power plants to ports on the east coast, the Australian Financial Review reported, citing an interview with Chairman Gautam Adani. The Indian company hasn’t had discussions with Hancock about buying a stake in its coal assets, the newspaper said, citing Adani.
